Multiple emails for Google Checkout orders

[Guest PLMaster]

We're running a patched 4.2.2. We've used Google Checkout fine for some time. Recently we started getting emails from Google saying it couldn't communicate with the cart anymore (odd since we hadn't changed a thing). So I went into CC admin and copied the XML address and put that into Google (instead of the one that had been in there that worked previously). In the past we would never get payment received emails from CC for GC orders, which was fine because we checked our GC account separately every day. Now we do, but we get three of the same thing for every GC order. PayPal and Authorize orders only send us one payment received email, but we get three from GC. Anyone had this problem and found a way to rectify it? It's annoying.

Thanks
